Fix rename of DBParameterGroup family for AdoptedResource (#89)

Issue #, if available:

aws-controllers-k8s/community#1264

Description of changes:

issue-1264 was due to `DBParameterGroupFamily` is not renamed to` Family` for `DescribeDBParameterGroups` operation. 
Adding corresponding rename so AdoptedResource of db param group can work. 

basically create and read `DBParameterGroup`/`DBSubnetGroup` operations should have same rename strategy, hence align all of them here  


Previous error is: 
```

```

After this update, no Reconciler error.
